    Sammanfattning : Anaerobic digestion and the production of biogas can provide an efficient means of meeting several objectives concerning energy, environmental and waste management policy. Interest in biogas is increasing, and new facilities are being built. LÄS MER

  2. 2. Nuclear Power as a Climate Change Mitigation Option: a Modelling Approach

    Författare :Mariliis Lehtveer; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; sensitivity analysis; nuclear weapons proliferation; energy system model; nuclear power; climate change;

    Sammanfattning : Although nuclear power can provide electricity with very low life cycle carbon emissions and thus reduce the cost of climate change mitigation, it also brings along many specific challenges: accident risk, need for radioactive waste management and nuclear weapons proliferation risk. Due to this controversial nature nuclear power, among other energy forms, has been relatively little studied in a climate mitigation context. LÄS MER

  3. 3. Proliferation resistances of Generation IV recycling facilities for nuclear fuel

    Författare :Matilda Åberg Lindell; Sophie Grape; Ane Håkansson; Staffan Jacobsson Svärd; Roland Carchon; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; safeguards; proliferation resistance; Generation IV; reprocessing; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : The effects of global warming raise demands for reduced CO2 emissions, whereas at the same time the world’s need for energy increases. With the aim to resolve some of the difficulties facing today’s nuclear power, striving for safety, sustainability and waste minimization, a new generation of nuclear energy systems is being pursued: Generation IV.

  4. 4. Biomass in a Sustainable Energy System

    Författare :Pål Börjesson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; economic valuation; environmental impact; carbon dioxide; Biomass; energy efficiency; Energiforskning; Energy research;

    Sammanfattning : The increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. LÄS MER
